Fig. 1From: COL6A3 polymorphisms were associated with lung cancer risk in a Chinese populationLinkage disequilibrium (LD) analysis of eight SNPs in COL6A3. The LD value is determined by r2 > 0.8 analyzed by Haploview software 4.2. The number in the diamonds is the LOD score of r2. Standard color schemes indicates different levels of LD. Bright red: LOD > 2, D’ = 1; Pink red: LOD < 2, D’ < 1; White: LOD < 2, D’ < 1Back to article page
